It is new generation of external modulated 1550nm Optical Transmitter from Uvins Technology. By adopting orginal band-new laser and external modulators from USA and Japan to Guarantee its good and stable performance during CATV and Digitla TV signal transmission over fiber network. this model is our high-end type, with pre-distortion circuit design to ensure its technical parameters can meet CNR≥53dB,CTB≥65dB and CSO≥65dB. , SBS 13-19dBm Adjustable for options during network setting..
With its stable performance and high technical parameters, this transmitter can be working with very good picture quality starting from 47Mhz-1000Mhz for long distance transmission for CATV and Digital TV network, and good choice for TV operators who want to solve the problems of poor picture quality in low frequency(47Mhz-200Mhz) signal transmission.
SNMP available for monitoring from PC.
